I have the Skip Hop Studio bag in "champagne" and after 2.5 years it still looks brand new. I never had a problem fitting everything I needed in it.
I just checked this bag out online and it's on sale for $65 at BRU right now! It looks really nice!
I agree with the PP who posted about Babysteals. I had my eye on the Babymel Amanda bag for a few months. I found it in the Babysteals archive a few weeks ago (not sure how I missed it on all of my previous visits to the archive) and ordered it for half price! Just waiting for it to come in.
Babysteals often has JJ Cole bags on it and sometimes PPB. I'm a fan of bags that don't look like diaper bags so that's why I went for the Babymel. As for the PPB bags, I just couldn't find a design that I liked.
